Question

intialised NSMutableString as below:

 -(NSString*)filterIt:(NSString*)source
{
    temp1= [[NSString alloc] initWithString:[source stringByReplacingOccurrencesOfString:@"rlm;" withString:@""]];
    //NSString *m_temp;
    temp1 = [temp1 stringByReplacingOccurrencesOfString:@"&" withString:@""];
    temp1 = [temp1 stringByReplacingOccurrencesOfString:@"#x" withString:@"&#x"];
    NSRange range = [temp1 rangeOfString:@"&#x"];
    NSRange range1 = NSMakeRange(range.location, 8);
    if (range1.location != NSNotFound) {
        NSString* temp2 = [temp1 stringByReplacingCharactersInRange:range1 withString:@""];
        //[temp1 setString:temp2];
        temp1 = temp2;
        range = [temp1 rangeOfString:@"&#x"];
        while (range.location < [temp1 length]) {
            range1 = NSMakeRange(range.location, 8);
            temp2 = [temp1 stringByReplacingCharactersInRange:range1 withString:@""];
            //[temp1 setString:temp2];
            temp1 = temp2;
            range = [temp1 rangeOfString:@"&#x"];
        }
    }
    //m_temp = [temp1 mutableCopy];
//  [temp1 release];
    return temp1;
}

if i try to release this string in dealloc method and try to run the app my app is crashing.

please give me some suggestions that how can i release this temp1

Thanks in advance
